The touch-screen display 162 of the mobiledevice cover 100 can provide the same or similar array of icons 164 asthe main display of the host mobile device 110, for example, or can becompletely different. This can be useful, for example, if the display ofthe host mobile device 110 is being used for another purpose (e.g.,playing a video, taking a call, work use, personal use, etc.), but theuser wants to access other mobile applications. For example, the hostmobile device 110 can be used to operate a GPS navigation application,while the mobile device cover 100 is being used to watch a movie or tostream video. Further, since the host mobile device 110 and the mobiledevice cover 100 can be in wireless communication, the mobile devicecover 100 can be detached from the host mobile device 110 while watchingthe movie or streaming video, for example.

Referring to FIG. 1A, when the host mobile device 110 is receiving anincoming call, for example, beads 180 that form the word “CALL” on theback cover 155 of the mobile device cover 100 can be illuminated, causedto flicker, flash, etc. If a calendar event notification is activated orreceived by the host mobile device 110, for example, the beads 180 thatform the word “ALERT” can be illuminated, caused to flicker, flash, etc.If a text message is received by the host mobile device 110, forexample, the beads 180 that form the word “TEXT” can be illuminated,caused to flicker, flash, etc. These events and others (e.g., socialmedia postings or messages, changes in sports scores, news items,emails, SMS messages, etc.) can also be displayed on the touch-screendisplay 162. The beads 180 can also be illuminated different colors andwith different intensities to indicate different degrees of urgency. Forexample, if the alert is urgent (e.g., an email sent with “highimportance”), the beads 180 that form the word “ALERT” can flash redand/or with increased intensity to indicate urgency. In another example,if the incoming call or text message is not from an important person,which can be designated via programming, user settings, userconfigurations, user preferences, etc., the corresponding beads 180 canbe illuminated a dim blue. In some embodiments, the mobile device cover100 can determine the identity of the caller or the message sender viaelectrical signals, sound signals, acoustic signals, wireless signals,digital signals, etc. received from the host mobile device 110. In someembodiments, the host mobile device 110 can determine the identity ofthe caller or the message sender and send a data signal corresponding toand/or identifying the caller or the message sender to the mobile devicecover 100 as well as other information (e.g., voice mail, text message,indications of importance, etc.). Further, the user may be notified asto the name, number, email address, etc. of the sender or source of thealert, text, email, or other notification via the lights 160, beads 180,or other output devices (e.g., speakers, screens, vibration, etc.) ofthe mobile device cover 100.

In some embodiments, the mobile device cover 100 can be configured toprovide video (e.g., live streaming video, streaming video, storedvideo, etc.) and/or other information (e.g., digital data, messages,news, alerts, etc.) on one or more screens. The video can be providedvia the host mobile device 110, for example, or some other source towhich the mobile device cover 100 and/or the host mobile device 110 isoperatively coupled. For example, the mobile device cover 100 can haveits own wireless link with an access point (e.g., an IEEE802.11-compliant access point) or a base station (e.g., a cellular basestation, a portable base station, etc.) from which to download mediacontent. The mobile device cover 100 can also include memory storage(e.g., non-transitory memory storage, solid state memory storage,removable memory sticks, disks, cards, etc.) on which resides mediacontent for playing or displaying on the screen of the mobile devicecover 100 and/or the host mobile device 110. The video can be, forexample, stored on the host mobile device 110 or can be streamed via awireless link (e.g., cellular link, WIFI link, IEEE 802.11 link,wireless local area network (WLAN) link, Bluetooth link, RF link, etc.)with a content provider or a third party application. In someembodiments, closed captioning or subtitles can scroll along the mainscreen 162 which can include and/or be supplemented with one or morescreens 132 on one or more edges 130 of the mobile device cover 100. Insome embodiments, the mobile device cover 100 can be configured toprovide an alert of a received video message and to play the videomessage on the screen 162 of the mobile device cover 100. The screen 162of the mobile device cover 100 can be substantially independent or cansubstantially mirror the screen of the host mobile device 110. Thescreens 162, 132 can be incorporated into the housing of the electronicdevice. Further, the screen 162 of the mobile device cover 100 can betouch-sensitive and employ graphical elements of a graphical userinterface. Thus, for example, a user input via the touch-sensitivescreen 162 of the mobile device cover 100 can provide a user input tothe host mobile device 110 and/or the mobile device cover 100. Thescreen of the mobile device cover 100 can be set up to substantiallymirror the screen of the host mobile device 110 or to operateindependently of the screen of the host mobile device 110. Content ormaterial can also be displayed on the mobile device cover 100 and/or thehost mobile device 110 that is from an application on the host mobiledevice 110, for example. For example, if the user has access to a sportsapplication running on the host mobile device 110 that shows sportsvideos, television channels, movie channels, or live events on the hostmobile device 110, the video may be displayed on the host mobile device110 and/or the mobile device cover 100.

Some embodiments provide that digital signals can be received orprovided by the host mobile device 110 and forwarded to the mobiledevice cover 100 for storage, processing, and/or output (e.g., on adisplay, lights, a speaker, a vibrating mechanism, etc.). For example,in addition to multimedia data, some embodiments provide that data(e.g., alphanumeric data, indicators, control data, source information,etc.) can be received or provided by the host mobile device 110 andforwarded to the mobile device cover 100 for storage, processing, and/oroutput. For example, the edge screen 132 (or any other screen or displaycomprising lights 160 on the mobile device cover 100) can be configuredto scroll information relating to news, sports, live or recorded eventsor movies, stocks, weather, calendar events, text messages, alerts,email, social media messages (e.g., messages or posts from mobileapplications or websites such as Facebook, Twitter, Snapchat, Instagram,etc.), etc. In some embodiments, the information can scroll around oneor more edge screens 132 around the mobile device cover 100. In someembodiments, the host mobile device 110 can be set to periodicallyreceive or retrieve sports data (e.g., scores, news items, etc.) orother types of data. The data can be from, for example, websites, mobileapplications, other host mobile devices, etc. The host mobile device 110can send sports data, for example, to the mobile device cover 100; andthe mobile device cover 100 can display or scroll the data across theedge screen 132 of the mobile device cover 100 or display or scroll onthe screen 162. In some embodiments, the edge screen 132 can betouch-sensitive, thereby allowing the user to tap or swipe an emailnotification and read a scrolling email on the edge screen 132 or onanother display (e.g., the main display 162 on the back cover 155) ofthe mobile device cover 100. In some embodiments, the data can flowacross the edge screen 132 in response to a finger sweeping motion alongthe edge touch-sensitive screen 132. In one embodiment, an incoming textmessage can be indicated by the beads 180 forming the word “TEXT” beingilluminated by lights 160, the sender of the incoming text can bedisplayed on the edge screen 132, and the text of the text message canbe displayed on the main screen 162 on the back cover 155 of the mobiledevice cover 100. In one embodiment, alphanumeric letters are displayedon the screen on the back cover 155 and the edge 130, eithersimultaneously or independently, indicating that a text message has beenreceived and possibly displaying the sender's name, the sender'sassociated icon (e.g., icon, emoji, animated icon, animated emoji,etc.), the sender's associated image (e.g., sender's picture), thesender's subject, the sender's header, the sender's body text, thesender's partial or full text, etc. A text or email icon can bedisplayed instead of the words TEXT, for example. The display can alsobe a series of LEDs forming a grid to accommodate lights show, scrollingtext, etc.

The edge screen 132 can be configured to scroll completely or partiallyaround the mobile device cover 100 and/or along one or more of its edges130. In some embodiments, the edge 130 can be segmented or partitionedso that the right edge portion is reserved for a first subject (e.g.,stocks), the left edge portion is reserved for a second subject (e.g.,sports), the bottom edge portion is reserved for a third subject (e.g.,email), and the top edge portion is reserved for a fourth subject (e.g.,calendar items, alerts, etc.), for example. Within each segment, theedge screen 132 can scroll the data. In some embodiments, the user canprogram and/or select which subject is displayed on each individualsegment on the mobile device cover 100. In some embodiments, the usercan program the mobile device cover 100 so that it decides on whichsegment to display a particular subject (e.g., incoming call, incomingtext, incoming email, incoming message, mobile device notification,mobile device accessory notifications, music or other audionotifications, social media notifications, etc.).

Referring to FIGS. 1B and 1C, the mobile device cover 100 can beadapted, for example, to provide physical vias (e.g., access openingsand windows) through which various input interfaces and outputinterfaces of the host mobile device 110 can be accessed withoutdetaching the mobile device cover 100 from the host mobile device 110.In some embodiments, the mobile device cover 100 may provide a physicalopening to access a display, a camera, a button, a control, otherinput/output (I/O) interfaces, etc. of the host mobile device 110. Insome embodiments, the mobile device cover 100 does not cover the maindisplay of the host mobile device 110 when the mobile device cover 110is attached to the host mobile device 110. In some embodiments, themobile device cover 100 may provide a transparent or partiallytransparent cover portion, for example, over a display or other portionsof the host mobile device 110. The transparent cover portion can be madeof materials that, for example, do not interfere with the operation ofany of the touch screens, speakers, and/or buttons of the host mobiledevice 110. In some embodiments, the materials can be substantiallytransparent to wireless communication links used by the host mobiledevice 110 and/or the mobile device cover 100. The transparent coverportion may also protect areas of the host mobile device 110 such astouch screens from scratches or other damage.

Some embodiments according to the present disclosure may provide thatthe mobile device cover 100 is made of one or more of the followingmaterials: silicone, rubber, metal, plastic, polymers, polycarbonate,composites, cloth, metal, wood, acrylic, glass, plexiglass, and/or othermaterials. The cover material may be, at least in part, opaque ortransparent. The cover material may assist a user in gripping the hostmobile device 110 and may protect the host mobile device 110. The covermaterial may be, for example, one or more of the following: shockresistant, shock proof, shatter proof, shatter resistant, dustresistant, dust proof, water resistant, water proof, etc. In someembodiments, the mobile device cover 100 may be made up of multiplepieces (e.g., portions 100 a, 100 b, 100 c, one or more printed circuitboards, housings, etc.), as shown in FIGS. 1B and 1C. In someembodiments, the multiple pieces of the mobile device cover 100interlock together to house, become the back panel of the host mobiledevice 110, and/or to connect (e.g., physically and/or electricallyconnect, snap, interlock, etc.) to the host mobile device 110.

Referring to FIGS. 1B and 1C, the mobile device cover 100 can include,for example, circuitry 150 and lights 160 disposed on one or moreprinted circuit boards. In some embodiments, the circuitry 150 caninclude one or more of the following: one or more processors, one ormore non-transitory memories, signal processors, light controlcircuitry, light drive circuitry, battery recharging circuitry, batterycontrol circuitry, display control circuitry, sensors, input interfacecircuitry, output interface circuitry, digital-to-analog converters,analog-to-digital converters, wired transceivers, wireless transceivers,input/output ports, input/output interfaces, and antennas. The one ormore non-transitory memories can be configured to store, for example,data (e.g., input data, data received from the host mobile device 110,stored reference data, stored configuration data, stored personal data,etc.) and processor-executable instructions or code for use with the oneor more processors. The circuitry 150 can be connected, for example, toand/or can include the lights 160. Some embodiments provide that thelights can include one or more of the following: LEDs, flexibleactive-matrix OLEDs (AMOLEDs), OLEDs, phosphor-based LEDs, white LEDs(WLEDs), multi-color WLEDs, semiconductor LEDs, other types of LEDs,LCDs, LCD touch screens, electroluminescence, pixel displays, etc., andcan be arranged or used in a specific pattern, array, sequence, etc.Some embodiments provide that the lights can be raised or provide bumpysurfaces suitable for use in a Braille system. Various components and/orelements of the circuitry 150 can be connected to each other through oneor more buses, for example.

The mobile device cover 100 can also include, for example, a battery 170(e.g., a rechargeable battery) that can be used to power, for example,the circuitry 150, the lights 160, and any other circuitry or componentsin the mobile device cover 100 and/or the host mobile device 110. Thebattery 170 can also be used to power the host mobile device 110 and/orto recharge a battery in the host mobile device 110. In someembodiments, the mobile device cover 100 does not have a battery andinstead can be powered by the host mobile device 110. Some embodimentsaccording to the present disclosure provide that the battery 170 can berechargeable or not rechargeable. If not rechargeable, the battery 170can be replaced. Some embodiments of the battery 170 include, forexample, a lithium battery, an alkaline battery, a silver-oxide battery,nickel cadmium battery, nickel metal hydride battery, lithium ionbattery, lithium ion polymer battery, etc. If rechargeable, then thebattery 170 can be recharged, for example, by drawing energy from one ormore interfaces of the host mobile device 110 (e.g., an audio port, anearphone jack, a docking port (e.g., a USB-type port, a lightningconnector port, a power and signaling connection port, etc.), a wirelesscharging pad, etc.). The battery 170 can also be recharged by drawingenergy separate from or independent of the host mobile device 110.Similarly, a rechargeable battery of the host mobile device 110 can becharged through one or more interfaces of the host mobile device 110that are electrically or wirelessly connected to the mobile device cover100. The rechargeable battery of the host mobile device 110 can also berecharged by drawing energy separate from or independent of the hostmobile device 110.

For example, independent of whether the mobile device cover 100 isconnected to the host mobile device 110, the mobile device cover 100 canbe separately plugged into a wall outlet or wirelessly charged at awireless charging station. The mobile device cover 100 can also becharged by plugging it into a computer, a charger bank, a generator,etc. via a USB-type connection, for example. The battery 170 of themobile device cover 100 can be charged by a piezoelectric batterycharger, for example. In some embodiments, the piezoelectric batterycharger can convert force (e.g., caused by pressure, movements,mechanical forces, etc.) into electrical energy for use by the battery170. Some embodiments contemplate converting other types of energy(e.g., sound energy, light energy, electromagnetic energy, magneticenergy, thermal energy, moving air, wireless energy, etc.) intoelectrical energy to charge the battery 170. In some embodiments, themobile device cover 100 can utilize charging methods such as conductiveand inductive charging.

In some embodiments, the battery 170 of the mobile device cover 100 canalso be recharged when the host mobile device 110 is wirelessly orwiredly connected to a power source (e.g., AC and/or DC power source).For example, the battery 170 of the mobile device cover 100 can berecharged when the host mobile device 110 is connected to a wall outlet,for example, such as when a docking port of the host mobile device 110is connected to a wall outlet. The battery 170 may receive energydirectly from the wall outlet (e.g., via connecting the mobile devicecover 100 directly to the wall outlet) or indirectly from the walloutlet through the host mobile device 110. In addition, the battery 170may receive energy when a docking port or some other interface of thehost mobile device 110 is connected to a computer while electrically orwirelessly connected to the mobile device cover 100. Some embodimentsaccording to the present disclosure contemplate that the circuitry 150receives power from the host mobile device 110 without using the battery170 or in combination with the battery 170. Thus, some embodimentsaccording to the present disclosure might not have a dedicated batteryas part of the mobile device cover 100, or might use the battery 170 asa back-up power source.

In some embodiments, just as the battery 170 of the mobile device cover100 can draw on energy from the host mobile device 110, the battery ofthe host mobile device 110 can draw on energy from the mobile devicecover 100 to recharge the battery of the host mobile device 110 or tosupplement power to the host mobile device 110. For example, asrechargeable batteries age, they are less capable of fully powering themain processor on the host mobile device 110. The aging batteries havereduced full charge capacity and provide less power, voltage, and/orcurrent during normal operation. As a result, some processors (e.g.,central processor, graphics processor, general processor, dedicateprocessor, etc.) will enter a power-save mode in which processor speed(e.g., clock speed) and/or load capacity (e.g., peak load) are reducedto conserve power and/or energy which is detrimental to performanceand/or inconvenient to the user. In such a situation, the host mobiledevice 110 can supplement the power and capacity of its own battery withthe battery 170 of the mobile device cover 100, thereby avoiding thepower-save mode of the processor of the host mobile device 110 or viceversa. Accordingly, the processors in the host mobile device 110 cancontinue to operate at normal operation speeds and load capacities.Further, by supplementing power and capacity of the host mobile device100, the battery 170 of the mobile device cover and the battery of thehost mobile device 110 can be used to power a turbo mode in theprocessor of the host mobile device 110 or vice versa. For example, inturbo mode, the processor (e.g., a central processor, a graphicsprocessor, a general processor, a dedicated processor, etc.) of the hostmobile device 110 can operate at one or more of the following: a highervoltage, a higher current, a higher power, a higher load capacity,and/or a higher clock speed than during normal operation. During turbomode, the host mobile device 110 and/or the mobile device cover 100 canoperate with greater performance and can perform moreprocessor-intensive applications.

In some embodiments, when the host mobile device 110 is electricallyconnected to the mobile device cover 100 (e.g., when the host mobiledevice 110 has been inserted into the mobile device cover 110) and themobile device cover 100 is plugged into a wall outlet, for example, thebattery 170 of the mobile device cover 100 and the battery of the hostmobile device 110 charge at the same time. In some embodiments, thebattery of the host mobile device 110 charges without a decrease incharge speed even when the host mobile device 110 and the mobile devicecover 100 are charged at the same time via the electrical connection(e.g., via a port 147) of the mobile device cover 100 to the wall plug,for example.

FIG. 1D shows an exploded side perspective view of an exemplary mobiledevice cover 100 according to an embodiment of the present disclosure.In some embodiments, the circuitry 150 can be embedded in the mobiledevice cover 100. In some embodiments, the circuitry 150 may include,for example, one or more circuit boards 150 a including, for example,one or more of the following: one or more processors, circuit elementsor components, an integrated circuit, an integrated circuit chip, asystem on a chip, etc. The circuitry 150 may also include, for example,one or more sensors 150 b (e.g., an audio sensor, a signal sensor, anoptical sensor, a wireless signal sensor, a wireless receiver, awireless transceiver, an electrical sensor, a power sensor, a batterysensor, an electromagnetic sensor, a vibration sensor, gyroscope sensor,iris scanner, fingerprint sensor, accelerometer, proximity sensor,barometer, hear rate sensor, a biometric sensor, etc.).
